Go buy powder this week. Stock up. I know its hard to find. But we're approaching take what you can get time. Maybe its not the best powder for your favorite load. So what? Most times you can find a safe load for just about any powder.
IEDs just went off on American soil. What are the odds they won't come after gun powder?
I sincerely hope I'm wrong. I'm not trying to be chicken little here. I'm just saying... it makes sense doesn't it? You don't have to be a conspiracy nut and think Boston was a false flag to see the writing on the wall. The powder ban is extremely predictable, and just to tempting for the politicians.
That's my advice. Take it or leave it.
